[0003] A tuning unit 2 extracts a signal of a desired reception channel from a television signal received by the antenna 1 and converts it into an intermediate frequency signal. The video processing unit 3 amplifies the intermediate frequency signal and performs video detection and generation of an intercarrier audio signal. The color signal reproducing unit 4 extracts a color signal from the video signal and outputs RGB signals necessary for operating the picture tube 7.
The three primary color signals are generated.

A synchronous deflecting unit 5 extracts a synchronous signal from a color video signal, generates horizontal and vertical deflection signals based on the synchronous signal, and operates a deflection circuit of a picture tube. The audio reproducing unit 6 detects the intercarrier audio signal and operates the speaker 8.

A driver circuit 17 is driven via a driver 18 and a Y driver 19, a low-pass filter 21 that passes a DC component of the signal of the photovoltaic cell 13, and a power supply circuit 22 that extracts power from the photovoltaic power of the passed DC component. .

Next, the operation will be described. In the transmitter A, the oscillation output signal of the oscillator 9 is modulated by the video signal A (see FIG. 2) input to the modulator 10, and the modulated signal becomes as shown in FIG. The light emitting element 12 emits light via the drive circuit 11 based on the signal b, and transmits the light to the receiver B.

In the receiver B, light is first received by the photovoltaic cell 13,
The video signal that has passed through the band-pass filter 14 is demodulated by the detection circuit 15, and the signal is as shown in FIG. At this time, the photovoltaic power other than the signal (photovoltaic power caused by disturbance light such as fluorescent light and sunlight) is removed. The DC component of the photovoltaic power passes through the low-pass filter 21 and is sent to the power supply circuit 22 to be power for driving the liquid crystal panel 20 and each circuit of the receiver B.

The video signal C demodulated in this manner is converted into an image signal for driving the liquid crystal panel 20 by the image converter 16, and an X driver 18 is provided by the driver circuit 17.
And driving the liquid crystal panel 20 via the Y driver 19,
Form an image. Thereby, the video can be viewed.

By performing the above-mentioned modulation, there is a function of preventing the influence of light other than the signal (disturbance light such as fluorescent light and sunlight), and the video signal can be transmitted reliably.

FIG. 3 is an external view of the wireless goggle vision device of the present embodiment. 23 is a photovoltaic cell 13 as shown in FIG.
And a screen unit integrally configured with the liquid crystal panel 20,
It is divided into right (R) and left (L). By doing so, it is possible to appreciate a stereoscopic image based on a stereo image. Reference numeral 24 denotes a frame to be put on the ear.
